AI War:AI Tachyon Sentinel

An immobile unit found camped out at wormholes, ready to uncloakscouts. When these are killed the AI won't build replacements, so you can use starships or your fleet to carve scouting paths for yourself if your scouts aren't able to progress in a given direction.

How to counter when in the AI fleet

Tachyon Sentinels are located in the wormholes of all the AI-controlled systems that aren't connected to a Human homeworld. Little more than a shadow of their former selves, the Tachyon Guardians, Tachyon Sentinels are a pushover, if barely, to keep scouts away from the AI's systems. They're a good way of practicing the art of Deepstriking (assaulting AI worlds deep within their territory).
